METAL can END.

This invention relates to pressed sheet metal ends for railway box cars. I p v gThe objects of the invention are to vide a sheet metal car end of a configura on that can be produced by die pressing and are exposed.

a vention will be apparent from the following specification.

Referring to the drawings, Fig. 1 is an elevation and front view of the car end as applied; Fig. 2 is an under plan view;

Fig 8 is a side elevation; Fig. 4 is a section onthe linelVIV of Fig. 1; andFig. 5

is a section on the line VV of Fig. 1.

For a number of reasons it is desirable to have sheet metal ends for ordinary'wood'en box cars. Many different forms of pressed plates have been employed for this purpose, the plates being pressed between dies to form corrugations, ribs, and other reinforcing configurations therein, for the purpose of giving rigidity to the end wall. t is for the same general purposes well-known in the art that the present structure is designed.

Referring to the drawings, the our end illustrated is made up of an upper plate 1 and a lower plate 2, joined together on a horizontal meeting line by overlapping flanges 8 and 4 at the meeting edges of the plates 1 and 2, respectively. These flanges are connected by rivets 5, so that in effect the two plates are formed into an integral structure. Except for a. slight difference in the flanges 3 and 4, to permit one toseat on top of the other, the plates 1 and 2 are identical and interchangeable. They may therefore be made from a common die, with a slight modification formed by a subsequent operation, to produce the necessary difference in the flange height.

The flanges 3 and 4 are raised from the base plane of the plates, and when riveted together form an effective reinforcing rib extending horizontally across the car end. Vertical reinforcing ribs 6 and 7 extend from the upper and lower edges of the two pia'testd' the ac-11 pai t me alisttrated in 1. These ribsftaper from the base plane of the,p'lat'e at {the upper and lower edges to the height of the "flanges aiid4 at the: middle portion. This is llusti'ated at the "left of F 4, which is 111 part a vertical section-along the rib '71 Diagonal reinforcing ribs 8, 8, and 9, 9, are provided in each of the plates, extending from the outer .corners thereof to the middle, and tapering upward from the plane of the plates to the height of the median rib formed by the flanges 8 and 4. The structure of one of these diagonal reinforcing ribs 8 is illustrated at the right of Fig. 4 and in end view at the middle of Fig. 2.

By the ribs 6, 7, 8, and 9, and the rib formed by the interfitting edges joined by rivets 5, the car end is divided into eight similar right triangles. All of these ribs are transverse in the sense that they extend across from edge to edge of the car end. The portion of the plate enclosed between the dividing ribs and the outer edges of'the car structure is formed in the pressing operatlon into a pyramid having sloping triangular faces a, Z), andc.

The sides of the plates are turned down i to form side flanges 10 for attachment to the side frames of the car body.

It will be observed that the structure illus trated and described divides the car end into four quarters, each of which is bounded on the two inner sides by a raised reinforcing rib. Each quarter is individually divided diagonally by a raised reinforcing rib, the

two halves of each quarter of the diagonal being stiffened by pressing the plate area betweenribs into a pyramidal shape. This arrangement gives great stiffness, while at the same time furnishing a structure that can be formed in two or four parts, or even in one part, by pressing properly sized plates between forming dies. There will be some drawing of the plates in this die forming operation, and that will result in maximum stiffness of the finished structure as will be readily understood by those familiar with the art.

I claim:

1. A car end formed of pressed metal plates comprising reinforcing ribs extending through the middle point and at right angles to the sides thereof additional reinforcing ribs constituting diagonals of the loo car end and raised pyramidal portions bounded by the diagonals and rectangular cross ribs.

2. A car end formed of pressed metal plates comprising reinforcing ribs extending through the middle point of the car end and at right angles to the sides thereof and reinforcing ribs constituting diagonals of the car end the portions of the plates between the said reinforcing ribs being raised and drawn into pyramidal form to give stifliness to the area so enclosed.

3. A car end formed of pressed metal plat-es, divided into a. plurality of triangles by transverse reinforcing ribs the triangular intermediate portions being pressed to pyramidal form.

4. A car end formed of pressed metal plates, comprising reinforcing rlbs extending through the middle point of the car end and 0 ribs, the diagonals and the vertical median 25 rib tapering from the outer edges to a maximum height at the middle portion of the car end. a a

5. A car end formed of pressed metal plates comprising transverse reinforcing 3i) ribs and raised pyramidal portions positionedin the spaces between said rlbs.

In testnnony whereof I sign my name.
